    [QUOTE=LS1_Dragster;107351]One of the issues is your throttle blade is not open enough. I knew you would have to crank on it to work with my tune. If you look at all your air parameters you are adding a ton more air then I am. Plus I like the IAC down in the 30 range. Also, my throttle body is a Holley so you might have to add air to my tune.

    Would it idle if you kept your foot on it? Also, is your MAF unplugged?

    By the way, the was a semi-open loop tune so LTRIM and closed loop enable should not of been changed.[/QUOTE

    Yes the MAF is unplugged
    I will be ordering a new injector to replace my #4 injector that leaks down fuel pressure into that cylinder, and then upon re-assembly I will crack open the throttle blade some more and play with the airflow at idle and try your tune again just to see what happens.
    Thanks for the your input!

    The flooded re-start issue is now fixed. The #4 injector was filling the intake with fuel fumes and that cylinder. I also replace the fuel pressure regulator and the lower intake manifold with a new one as well while I had it off.

    Thank you guys for your input!
